Re: QBL 5/3500 with G2DAF ?
In my experiences, the G2DAF design is c. 11db cleaner with a 2-tone modulation test than it is with voice modulation. Wi

Re: QBL 5/3500 with G2DAF ?
Peter, It might be a good idea to contact SM2CEW http://www.sm2cew.com/ampli.html If it costs already a lot of time and money I would invest 100 more Euros (for new Parts) in a well regulated screen

Good afternoon List ! I'm new to the list. Today I got a tip G2DAF experts might be around here. From various sides I got incompatible advices on the G2DAF concept for a HF linear ( SSB speech ) PA

Re: L-4B parasitic supressors
Bob, I think I ditched the idea with a fuse. What the heck, if my 8171 box doesnt have a fuse why bother with this toybox. 73 SM2EKM ------------- Robert B. Bonner wrote:

Re: L-4B parasitic supressors Drake mods galore.
I see. Well its getting strange. As I wrote before, in the manual I have someone had written 15 ohms on the schematic, there is no parts list in the manual. However I have two L-4Bs here and I see now

Re: Mother Mary... save us all.... from parsitic hell.
Jim == The suppressor resistors are paralleled with c. 80nH of L. What frequency would be required to develop enough V-drop across 80nH to fry the resistors?

Re: Mother Mary... save us all.... from parsitic hell.
I must put this right. 15 ohms was wrong, sorry! Explanation: Since I have no manual I have found one on internet, on the schematic someone has scribbled with a pen 3 x 15 ohms for the resistors,

one sees obliteration, it usually means VHF oscillation. ### No it doesn't. With his 3 x paralled 15 ohm resistor's... it means he has 5 ohms in total.... and the wrong value to start with ! The goals
